Frictional Properties of DLC films in Plane Contact due to Reciprocal Micro-Sliding

The objective of this research is to investigate the frictional behavior of a-C:H coating in plane contact by using reciprocating micro-sliding test under controlled relative humidity. The friction tests were conducted at various relative humidities (RH) between 5% and 90% without lubrication at roo...
